The undefeated Los Rojiblancos now lie second in La Liga, two points behind Barcelona as they look to capitalise on boasting arguably the best out-and-out striker in the league.

The 60 points gained push them three places up to seventh, just behind Chelsea, who also picked up a decent points tally following their excellent win at Arsenal.

As a result Porto, Borussia Dortmund and Arsenal slide down, but they all remain in the top 10 unchanged. The five leading sides — Barcelona, Real Madrid, Manchester United, Bayern Munich and Manchester City — do not move, although United's defeat means they have lost touch somewhat with the Spanish duo.

The only new entry this week are Dutch giants Ajax, who replace Lyon in the lower reaches of the 20.

HOW IT WORKS

To determine our Power Rankings, we use the Euro Club Index, which scientifically analyses hundreds of thousands of matches from the top divisions in all European nations as well as Europa League and Champions League games.

The Index takes into account all matches played over an eight-year period but with recent results carrying more weight than older ones.

The performance of a league's teams in the Champions League and Europa League reflects the rise or fall of the sporting level in that league.

So, for example, if English teams perform well in Europe, all Premier League teams receive a small bonus in their ECI score. The ranking and its predictive power are thus made even more accurate.
